' METAL SHEATHING FOR FIRE-WALLS."

Specification of Letters Patent.

resented April 17, 1906..

Application filed December 16 1905. Serial No. 292,064.

To all whom it may concern:

Be it lmown that I, WILLIAM R. Ross, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Im rovements in Metal Sheathing for Fire-Wal s, of which the following is a specification.

My invention relates to metal sheathing or covering for that portion of the arty or fire wall projectin above the roofs 0 buildings.

It is desira le and is now enerally the practice to sheath entirely wit metal such portion of the wall; and it is the object of the present invention to provide a sheathing that maybe ap lied expeditiously, is economical of materia and obviates all. difficulty arising from the settling of new building construction.

In the embodiment of my invention as herein described, and illustrated in the drawings forming a art of this specification, I have shown the device in its applicationto a building construction in which what is known in the art as a slag roof is employed, though it is manifest that the'invention is applicable in conjunction with other forms of roofing.

Referring to the drawings, Figure 1 1s a wall provlded with my improved sheathing. Fig. 2 is a perspective view showing the parts comprisin my improvement in their relative int in detached relation. 3 is a sectional view of the various parts 'of the sheathing in associated relation and with the roofin material a plied.

.Int eflgures, 1 esignatesthe fire-wall, and 2 the roof.

3 is a layer of tar paper or felt usually employed as a primary covering for the roof in constructions of the character referred to. i

4 is asheet-metal coverin or flas for the side wall, having a flange portion 5 ying upon the roof and preferably over the tar paper, where it is secured by nailing or otherwise. The free end of the flashing is terminated a short distance below the top of the wall for the pu ose hereinafter stated.

6 is a strip of s eet metal of suitable dimensions to cover the to of the wall and permit 3f bein1 beit over tli 1 fr e en 1 an es7 overa the eeed e of the fl i g Slits or ggi'figrations S a e formed at suitable intervals in the sheetmetal to cover, preferably near or at the bend in t e metal.

e sides thereof to form- 9 desi nates flexible sheet-metal cleatsof suitable ength to be nailed to the roof and extend along the roof and u the all beneath the flashin and flange portion of the through the slits therein, 6:;

top cover to an where they are secured y 'being bent over, as shown. The engaging parts are .then soldered to render the same secure and water'- tight. The method of securing the cleats to the cap-piece herein shown has been found most satisfactory, though manifestlyother means within the scope of my invention may be em loyed. 10 esignatesslag or other roofing material ap lied to the roof and over the portion of the ashing lying thereon.

The cap-piece having been placed in osition, the cleats are nailed to the roof and cut to conform to the angleof the roof and the wall. They are then passed throu h the slits in the top cover. The flashing, a so bent to conform to the angle of the roof and wall, is then placed in position. Then the projecting edge of the top cover is bent over upon the flashing and the protruding end of the cleats hammered down. The slag or roofing material proper is then applied over the roof and portlon of the flashing lying thereon and filled up close to the wall.

In the settling of new buildings caused by seasonin of the timber, drying of green mortar, weig t of the roof, and other causes there is more or less relative displacement of the roof and fire-wall. My wall-covering being made in two ieces free tom'ove with the parts to which t ey are secured and relatively to each other, the buckling and tearing of the parts is obviated. The flashing being secured. only to the roof is free to move up or down beneath the flanged portion of the top cover 9 should there be any movement of the wall or roof. The metal cleats being secured to both the wall-cover and the roof, it is necessary so to construct and apply the cleats that upon the settling of the roof they will not be no torn from their fastenings. By constructing .1

the cleats of flexible metal and securin them to the roof at a point removed from t e wall upon thesettling of the roof relatively to the wall, which is the usual occurrence, the cleats 105 does not materially aii'ect the eficiency of the i re roofcovering, thoughthere may be some slight displacement of the roofing material lying adjacent the Wall. 7

What I claim is 4 I 1. A metal sheathing for fire-Walls comprising a flashing secured to the roof and havmg a free edge terminating below the top of the Wall, a top cover for the Wall having de pendin flanges overla ping the free edge of the flas ing, and fieXib e metal cleats secured to the top cover, extending beneath the flanged portion thereof and the flashin and secured to the roof" at points removed from the Wall.

2. In building construction, a fire-Wall, a

flashing secured to the roof and having a free edge terminating below the top of the Wall, a top cover for the fire-wall having de ending flanges overlapping the free edge of t e flashing, flexible metal cleats secured to the top cover',-extending beneath the flanged ortion thereof and the flashing, and secure to the roof at points removed from the wall, and a roofin material overlyin the roof and portion 0% the flashin lyin t ereon.

In testimony W ereo% I aflix my signature in the presence of two Witnesses.
